3 Aims Objectives Outcome Explain how underfloor heating works Explain how underfloor heating works Examine advantages & disadvantages of various heating systems Examine advantages & disadvantages of various heating systems Introduction Provide solutions to common heating problems Provide solutions to common heating problems Resolve factors affecting specification Resolve factors affecting specification Show how you and your clients can benefit from UFH Show how you and your clients can benefit from UFH Effect energy efficiency improvements Effect energy efficiency improvements

4 How do modern heating systems work?

6 Basic principles Radiators Transfer heat from very small & very hot surfaces (750C) to the room (200C). High rate of convection. UFH Transfers heat from a surface slightly warmer than the room (290C to 200C) Very high rate of radiation. Natural, comfortable warmth.

7 Modern Underfloor Heating Mainly warm water Mainly warm water High tech plastic pipe in or just below floor High tech plastic pipe in or just below floor Water is O C Water is O C Forms to suit most floor constructions Forms to suit most floor constructions Well proven controls Well proven controls Economical to run Economical to run Reliable, long lasting Reliable, long lasting Maintenance-free Maintenance-free

12 Suspended Floor Construction

13 Cross-batten wooden suspended floor

14 Floating Floor Construction

15 Floor Cross Section

16 S Plan layout

17 Familiar Technology 20°c

18 How do Radiators Work? Stratification leads to higher temp. and thus high heat loss 27°C 20°C 19°C 17°C 50°C 17°C HIGH HEAT LOSS THROUGH WINDOWS

19 How does UFH Work? Just like one big low temperature radiator 27°C to 29°C 20°C

20 Energy Savings with Underfloor Heating No hot air in front of glass No hot air in front of glass = Less heat loss through window No hot air at ceiling level No hot air at ceiling level = Less heat loss through ceiling & wall Lower air temperature for same comfort Lower air temperature for same comfort = Reduced number of air changes Uses lower water temperature Uses lower water temperature = Lower transmission losses Options to use non-fossil fuel heat sources Options to use non-fossil fuel heat sources and boilers in condensing mode

21 Advantages of UFH Advantages of UFH Very comfortable Very comfortable No hot heads or cold feet No hot heads or cold feet Does not promote floor draughts Does not promote floor draughts No drying of the air No drying of the air Reduced dust levels Reduced dust levels Unobtrusive Unobtrusive Walls left completely clear Walls left completely clear Floors and walls are easier to clean Floors and walls are easier to clean

22 Other Advantages of UFH Quiet No creaks and groans, especially in solid floors Safe No hot surfaces - important to HSE No sharp edges to cause injury This is the Ultimate low surface temperature radiator Nothing to vandalise (In Sweden only UFH is allowed, by law, in Children's nurseries)

24 Observation Radiators were a great advance when the alternative was to have a open grate in every room... and now UFH is the ultimate radiator

25 Summary Underfloor Heating today is:- Clean and green Comfortable Invisible Quiet Safe Energy-efficient Maintenance-free UFH has come a long way, and is right for the UK too!

26 WHAT CAN DO FOR YOU?

27 We offer a complete package Quotation Design Installation Commissioning Full system documentation 25 year warranty After Care Support

28 Your client will have the advantage of: Running costs considerably lower Running costs considerably lower Reduced heat loss at windows and ceilings Reduced heat loss at windows and ceilings Lower air temperature more comfort Lower air temperature more comfort Lower water temperature Lower water temperature

29 What do we need from you Design criteria and specification Design criteria and specification Drawings – CAD format Drawings – CAD format Integration into your build programme Integration into your build programme Unimpeded access to floor areas Unimpeded access to floor areas (for a short time) Systems need to be covered immediately after installation to avoid damage Systems need to be covered immediately after installation to avoid damage Communication – co-operation Communication – co-operation
